Be it known that I An'rut'e COLLINS Atjs- 1121:. a subject of the King of Great Britain, 5 residing at Crown Works. Barford street,! :Birmingluun. England. have invented certain new and useful lmproveinentsin Hinge- Joints for Folding Wind-Screens, of which I the following is a specification.

This invention has relation to'joint-s or hinges for use in connectionwith folding or adjustable windscreens and other folding or adjustable fittings or attachments for automobiles and other ,vehicles; such joints or hinges being of that type which embody means for positively locking'the two knuchits or parts to one another, and in any relative angular position, through the medium of systems of radial teeth or the like which are t-aken'into and retained in engagement by the action of a screw orequivalent device.

The principal object of the present invcn tion is to provide an improved construction of lock action hinge or joint in which the en-' gagement and disengagement. of the radial 1 locking teeth can be effected without involving any lateral movement of either of the two principal knuckle elements of the joint and without necessitating-the lateral displacement of the screen or other fitting of which the said joint forms a part, This object I propose to realize rincipa-llv by 'an' arrangement wherein teeth -or rojections so disposed as to admit of the. two sets being collectively engaged by correspondin teeth or recessesion a single locking, coupor keeper device which, when in its elleetive' position, serves to lock the said'knuckles to one another and to therebv positively secure the hinged parts of the justable screen or the like at any desired relative angle or inclination.

Figure 1 of the accompanying drawings represents a part of a folding wind screen grovided with 1m roved joints constructe in accordance with this invention. Fig. a side elevation of one of the 'oints of the said screen, showing how the loc 'ng'or engaging elements are separated so that the joint can be adjusted to any desired angle. Fig, 3 represents a vertical section of the 'oint in its locking position. Fig. 4 is a sim' at view showingthe same unlocked, and the engaging part-s separated. Fig. 5 shows the-variouscomponentparts separated. Fig. 6 is a view of another form in which the locking l formof joint.

element is loose upon its pin. Fig. Z represents a section of a modified form of joint constructed in accordance with this invention. Fig. 8 is a section of another modified Fig. 9 is a section of a joint constructed in accordance with a further modification.

Referring to the construction shown in Figs. 1 to 5, the face of the knuckle or element 0 of the joint: is provided with a laterally-projecting sleeve or bush a, whose end face [5 out with teeth a; radiating from the center of a pin 0 which is d through said bush. This sleeve or bus serves as the hearing for the other element 6 of the joint, whose knuckle takes the form of a ring or eye b that surrounds, and is capable of turning upon, said bush in adjusting the relative angle of the two parts of the joint. The inner face of this ring knuckle is plain, and lies and works a ainst the corresponding lain face of the uckle awhile the outer ace of the said ring knuckle is designed to fall in the same plane as the serrated face of said bush or sleeve a and is also formed withteeth or serrations b radiating from the same center as those of the latter. By this er rangement, there is provided on the outer faces of the knuckles, two concentric rings of face teeth or serrations a" b, and the locking:- of the said knuckles at anj desired relative an is is effected 'by -means of a washer or p ate d which is fast upon the pin and has, upon its inner side, long radial teeth or serrations d whichafter the adjustment.-

of the hinge-are'adapted to be engaged collectively or-in common with the concentric'rings of teeth or serrations a, b, on the two knuckles and to thereby establish a posithe union or locking connection between them. The pin 0 is screw-threaded and is passed throu h a hole a in the knuckle a and is actuated, or moving said locking plate (1 laterally into and out of engagement with the two knuckles by the action of a wing or other nut e which is screwed on the outer end of the pin 0, and takes a bearing againstthe face of the knuckle a. To facilitate the lateral separation 'ofthe toothed parts and to disconnect the two knuckles, a springf is arranged to surround the pin and be coinressed between opposed lain parts of the ocking or coupling plate and the bearing bush 0 when the parts are. drawn together, whereas when the nut e is unscrewed, the spring expands sufliciently to clear the teeth -work within an internally screw-t the said of the plate (3 from the two sets 'of teeth 12 12*, on the knuckles. Instead of the locking plate d bein fixed upon its pin c, it may be carried loose y thereon as representedin Fig. 6. In the arrangement shown in Fig. 7 the lockin late 11 provided with the radial teeth IS loose mounted on the outer end of the pin or bo t c, which carries the fixed handle or grip e, at its outer endthe said pin being screw-threaded and adapted to readed hole a in the member a of the joint. By this means as the in or bolt is rotated by 'p e, the ockinfi plate or washer d is cause to move Ia'tera y to engage with the rings of teeth a, b.

In the modification shown in F i 8, the

' pin 0 is provided .at its inner end, wit a head tions as shown. When the said washer isc which bears a ainst the back of the member a, while the ocking plate or element d is loosely strung upon the outer end of said m; and its locking teeth are adapted to be t en collectively into engagement with those of the joint members by means of the internally screw-threaded boss of a handle or grip member e, which is screwed on to said pin 0. The pitch of the teeth a may be greater than that of the teeth b as shown while the inner ring or portion (1 of the teeth of the locking element d are formed of corresponding increased gitch so as to engage with the said teeth a. y this means the teeth of the one part are more readily led into engagement with those of the other part. 1

In .the modification shown in F i 9, the outer ring of teeth 6 are formed ra ial as in the preceding forms, whereas the bearingbush a is coned at a on its outer i ace and the said coned surface formed with radial teeth or serrations a. The locking washer or plate d, (which is carried 'b the screw-threaded pin. c), in addition to aving radial teeth d near its periphery to e age with the teeth so provided with a moved laterall by the action of the nut e, the cone a soc ets into the-engaging coned part (1., so that the two sets of teeth engage with one another simultaneously with the en agement of the teeth d and b.

iaving full described our invention, what we desire to c aim and secure by Letters Patent is:-

1. In a hinge joint of the type set forth, in combination, two joint members having rotatabl assembled and related hinge portions provi ed with annular concentric rows of teeth, a laterallymovable locking member having teeth on one of its side i aces for common engagement with the teeth of said hinge portions, and means for adjusting said lock-1 in member axially tower and away from said hinge portions to engage -or disengage having teeth on one of its side faces for common engagement with the teeth of said hinge portions, means for. adjusting said lockin member axially toward and away from sai hin e portions to engageor disengage the teat thereof and 8 ring means inte osed between the inner inge portion an the looking member and acting to assist in iorcing the latter outwardly.

3. In a hinge joint of the type set forth, in combination, two joint members, one having a laterally extendmg bearing and the other having a ring portion surrounding said bearing, said bearing and said ring portion being formed with concentric annular rows of teeth, an axially movable plate having looking teeth on one of its side faces for common enmeans for adjusting said. late toward and away from said joint mem ers to engage or disen age said teeth.

4. In a hinge joint of the type set forth, in combination, two joint members having rotatabl assembled and related hinge portions provided with annular rows of teeth one within the other -an axiall adjustable pin and a plate loosely mounte on said pin and having locking teeth for common engagementwith the teeth of said hinge portions.

5. In a hinge joint of the type set iorth,in combination, two joint members having hinge ortions formed with looking teeth, one of sai hin e portions .being conical in form, and the ot er hinge portion being of ring form and surrounding the conical ortion, a

locking plate having a conical soc 'et to re- I ceive the conical hinge portion and having also teeth for engagement with the teeth of said hinge portions and means for ad 'usting said plate toward and away from sai hin e portions to engage or disengage said test 1.

'gagement with said first named teeth, and a In testimony whereof I have hereunto set w my hand in presence of two subscribing witnesses.
